Atthe a hub portion or by the rotation ofv the handle M beginning of thismotion, the tooth (Z of the 1 member E is situated between two teeth ofance, but the member E compresses the two' springs allowing the tooth dto overcome this resistance and to cross over the next tooth.

It must be noted that, at this time, if the rotative motion werestopped, the window would stay in its position, for the springs have anaction which is slightly superiorvto the action-transmitted to the leverL by the wei 'ht of the window. As soon as the tooth (Z is between twoteeth of the boX B, the system stops, the'spring p being then slightlyprevailing, and the window is unable to move from the position that hasbeen fixed to it.

v During'the rotative motion hereabove described, the teeth of the wheel1" mesh with the teeth of the rack C, and cause itto advance in thedirection of the arrow. It gives the lever L by the intermediate of thepin a rotative motion about the pin O whilst the lever L acts upon thewindow which is led laterally, and the pin comes to a convenientposition, in the slide bar. The stirrup A has obviously moved duringthis motion round the shaft (2. v v

This invention allows therefore by a'very simple movement, to give thewindow any desired position without fear that it will move under itsownweight or due to shocks.

Instead of using the intermediate apparatus between the handle and therack, that is illustrated in the Figures 1 to 7, I prefer to empoy themechanism shown-in Figures 8 to The shaft 9 (Figures 4, 5, 6 and 7) isprovided with a head t, and is splined as at m; and m and is providedwith a screw hole V to receive the handle This shaft passes through thestirrup A and then the toothed wheel 1", which is formed in one withsleeve having two flats m and m 7 On the shaft (2 is a member E adaptedto engage with the two flats m and m of the wheel 1", and which (Figure13) is provided with an eccentric hole to for the passage of the shaft 9and in addition with a slot T for receiving a pin a carried bythe shaft(2.

lVhen the member E has "been placed inposition Figure 11) there isplaced on its front part a frame G of arcuate form, which butts Iagainst each end of the pin a. In this frame are rollers 9 and gbetweenwhich is inserted aspring R that is held in position by a coverpiece B, secured to the plate F The handle M is finally mounted on theheady T and secured in position by a screw The window is moved to openor close 7 which causes the rotation of the toothed wheel 1, inengagement with which is the raclr G pivotally con- 5 nected to thewindow supporting lever The operation of the mechanism is as follows(see more particularly Figures 8 to 13). Suppose the window to have beenmoved to an open position where under the action of its own weight orvibration it tends to fall, ro-

tary movement in the direction of arrow- (Figure 3) is transmitted bymeans of the rack C to the toothed wheel 1 and the member E inengagement with the flats m and m formed on the hub portion of the wheel7".

The member E owing to it. being eccentrically mounted on the shaft 9will on rotation wedge the roller g against the inner surface of thecasing B, when further movement of the wheel 7 is prevented, and thewindow is held fast. b

On the rotation of the handle in the same direction, the pin a carriedby the shaft 9 will engage the left hand end of the frame Gr, in whichare mounted the rollers g and g and the whole that is frame G and memberE will rotate within the casing B, the wheel r which is connected to themember E also rotating to operate the window.

It is evident that rotational movement in the reverse direction'willhave the effect of causing the roller 9 to wedge itself in place of theroller the operation is thus identical in the two directions. 7

The present invention thus permits, by a very simple movement, withoutusing any force, of moving the window to any desired positionwithoutfear that the latter will move under its own weight or due toshock.

It has in respect to the systems already known the advantage of a verysimpleoperation, and low cost. v

, Having now particularly described and ascertained the nature of mysaid invention, and in what manner the same is'to be performed, Ideclare that whatfI claim is r 1. In a combined -window regulatorandlocking device, a casing adapted to be secured to the window support, ashaft journaled in the casing, a handle for rotating the said shaft,agear loosely fitted on the said shaft and provided with a sleevedextension, a combined actuating and locking member carried by the saidshaft and adapted to cooperate with the said sleeve and casing forpreventing rotation of the said gear, means for normally holding thelocking member in locking engagement with said casing, said lockingmemher being shiftable by the said shaft incident to rotation thereof tocause disengagement of said locking member from the casing andsubsequently establishing driving relation through the locking memberbetween the said shaftand said gear extension.

2. In a combined window regulator and locking device, a casing, adaptedto be secured-to the window support, ashaft journaled in the casing, ahandle for rotating-the said shaft, a gear loosely fitted on the said ashaft and provided with a sleeved extension,

a cam member provided with a channel on one face and splined to the saidsleeved extension, said cam member being loosely carried by the saidshaft, lateral extensions on said shaft projecting into the channel inthe cam and adapted to establish driving relation between the shaft andthe gear through the cam member, and an areuate member interposedbetween the said cam and said casing and engaging the said shaftextensions, said arcuate member having means adapted to be wedgedsecurely against the casing by the cam, thereby preventing furtherrotation of the gear, and being shiftable by the said shaft extensionsto cause release of said cam member to permit rotation of the said cammember by said shaft extensions.

In testimony whereof I affix my signature.
